text: "Zusammenfassung\r\n Aufgrund
aktueller Transformationsprozesse kommt der automatisierten und ressourceneffizienten
Fertigung hochfester Leichtbauteile eine steigende Bedeutung zu, beispielsweise
im Flugzeug- und Fahrzeugbau. Für kleine Losgrößen bietet sich hier insbesondere
das Fertigungsverfahren des Drückwalzens an. Der konventionelle, industriell genutzte
Drückwalzprozess stößt allerdings aufgrund der Prozesskomplexität hinsichtlich
der Reproduzierbarkeit an seine Grenzen. Dies wird in der Praxis teilweise durch
personengebundenes Erfahrungswissen kompensiert. Auch ist es nicht möglich, Bauteileigenschaften
definiert einzustellen. Aus diesem Grund bietet der Einsatz einer neuartigen Eigenschaftsregelung
Chancen zur Weiterentwicklung des Fertigungsprozesses und die Möglichkeit zur
Prozessautomatisierung. Hier werden die Werkzeugbahnen abhängig einer Online-Eigenschaftsmessung
über eine zusätzliche Reglerkaskade manipuliert. Die Entwicklung einer solchen
Eigenschaftsregelung erfordert den Einsatz geeigneter, modellbasierter Entwurfsmethoden.
In diesem Beitrag wird daher ein regelungstechnisches Systemmodell für das Drückwalzen
metastabiler austenitischer Edelstähle vorgestellt. Das Simulationsmodell weist
aufgrund seiner Echtzeitfähigkeit neben dem Einsatz als reines Entwurfsmodell
weitere Nutzungsmöglichkeiten z.B. in Beobachtern auf und grenzt sich somit von
domänenspezifischen Simulationstools wie der FEM ab."

text: Abstract. Climate change, rare resources and industrial transformation
processes lead to a rising demand of multi-complex lightweight forming parts,
especially in aerospace and automotive sectors. In these industries, flow forming
is often used to produce cylindrical forming parts by reducing the wall thickness
of tubular semifinished parts, e.g. for the production of hydraulic cylinders
or gear shafts. The complexity and functionality of flow forming workpieces could
be significantly increased by locally graded microstructure and geometry structures.
This enables customized complex hardness distributions at wear surfaces or magnetic
QR codes for a unique, tamper-proof product identification. The production of
those complex, 2D (axial and angular) graded forming parts currently depicts a
great challenge for the process and requires new solutions and strategies. Hence,
this paper proposes a novel control strategy that includes online measurements
from an absolute encoder to determine the angular workpiece position. Workpieces
of AISI 304L stainless steel with 2D-graded structures are successfully manufactured
using this new strategy and analyzed regarding the possible accuracy and resolution
of the gradation. At this point, a dependency of the gradations on the sensor
and actuator dynamics, accuracy and geometry could be noted. It is further evaluated
how the control strategy could be extended by an observer-based closed-loop property
control approach to enhance the accuracy of the suggested strategy.

text: Abstract. Workpiece property-control permits the application-oriented
and time-efficient production of components. In reverse flow forming, for example,
a control of the microstructure profile is not yet part of the state of the art,
in contrast to the geometry control. This is, due to several reasons, particularly
challenging when forming seamless tubes made of metastable austenitic stainless
AISI 304L steel. Inducing mechanical and/or thermal energy can cause a phase transformation
from austenite to martensite within this steel. The resulting α’-martensite has
different mechanical and micromagnetic properties, which can be advantageous depending
on the application. For purposes of local property control, the resulting α’-martensite
content should be measured and controlled online during the forming process. This
paper presents results from the usage of a custom developed cryo-system and different
application strategies to use liquid nitrogen as a coolant for local enhancement
of the forming-temperature depending α’-martensite content.

text: AbstractThe constantly increasing challenges
of production technology for the economic and resource-saving production of metallic
workpieces require, among other things, the optimisation of existing processes.
Forming technology, which is confronted with new challenges regarding the quality
of the workpieces, must also organise the individual processes more efficiently
and at the same time more reliably in order to be able to guarantee good workpiece
quality and at the same time to be able to produce economically. One way to meet
these challenges is to carry out the forming processes in closed-loop control
systems using softsensors. Despite the many potential applications of softsensors
in the field of forming technology, there is still no definition of the term softsensor.
This publication therefore proposes a definition of the softsensor based on the
definition of a sensor and the distinction from the observer, which on the one
hand is intended to stimulate scientific discourse and on the other hand is also

text: "Abstract\r\n This paper presents
the characterization of the microstructure evolution during flow forming of austenitic
stainless steel AISI 304L. Due to plastic deformation of metastable austenitic
steel, phase transformation from γ-austenite into α’-martensite occurs. This is
initiated by the formation of shear bands as product of the external stresses.
By means of coupled microscopic and micromagnetic investigations, a characterization
of the microstructure was carried out. In particular, this study shows the distribution
of the strain-induced α’-martensite and its influence on material properties like
hardness at different depths. The microstructural analyses by means of electron
backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite
(ca. 23 %) close to the outer specimen surface, where the plastic deformation
and the direct contact with the forming tool take place. In the middle area (ca.
1.5 mm depth from the outer surface), the portion of transformed α’-martensite
drops to 7 % and in the inner surface to 2 %. These results are well correlated
with microhardness and micromagnetic measurements at different depths. EBSD and
atomic force microscopy (AFM) were used to make a detailed characterization of
the topography and degree of deformation of the shear bands. Likewise, the mechanisms
of nucleation of α’-martensite were discussed. This research contributes to the
development of micromagnetic sensors to monitor the evolution of properties during
flow forming. This makes them more suitable for closed-loop property control,
which offers possibilities for an application-oriented and more efficient production."

text: The production of complex multi-functional, high-strength parts is
becoming increasingly important in the industry. Especially with small batch size,
the incremental flow forming processes can be advantageous. The production of
parts with complex geometry and locally graded material properties currently depicts
a great challenge in the flow forming process. At this point, the usage of closed-loop
control for the shape and properties could be a feasible new solution. The overall
aim in this project is to establish an intelligent closed-loop control system
for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces
in a flow forming process. To reach this goal, a novel sensor concept for online
measurements of the wall thickness reduction and the martensite content during
forming process is proposed. It includes the setup of a modified flow forming
machine and the integration of the sensor system in the machine control. Additionally,
a simulation model for the flow forming process is presented which describes the
forming process with regard to the plastic workpiece deformation, the induced
α’-martensite fraction, and the sensor behavior. This model was used for designing
a closed-loop process control of the wall thickness reduction that was subsequently
realized at the real plant including online measured feedback from the sensor
system.

text: One of the main objectives of production engineering is to reproducibly manufacture
(complex) defect-free parts. To achieve this, it is necessary to employ an appropriate
process or tool design. While this will generally prove successful, it cannot,
however, offset stochastic defects with local variations in material properties.
Closed-loop process control represents a promising approach for a solution in
this context. The state of the art involves using this approach to control geometric
parameters such as a length. So far, no research or applications have been conducted
with closed-loop control for microstructure and product properties. In the project
on which this paper is based, the local martensite content of parts is to be adjusted
in a highly precise and reproducible manner. The forming process employed is a
special, property-controlled flow-forming process. A model-based controller is
thus to generate corresponding correction values for the tool-path geometry and
tool-path velocity on the basis of online martensite content measurements. For
the controller model, it is planned to use a special process or microstructure
(correlation) model. The planned paper not only describes the experimental setup
but also presents results of initial experimental investigations for subsequent
use in the closed-loop control of α’-martensite content during flow-forming.

text: The implementation of control systems in metal forming processes improves
product quality and productivity. By controlling workpiece properties during the
process, beneficial effects caused by forming can be exploited and integrated
in the product design. The overall goal of this investigation is to produce tailored
tubular parts with a defined locally graded microstructure by means of reverse
flow forming. For this purpose, the proposed system aims to control both the desired
geometry of the workpiece and additionally the formation of strain-induced α′-martensite
content in the metastable austenitic stainless steel AISI 304 L. The paper introduces
an overall control scheme, a geometry model for describing the process and changes
in the dimensions of the workpiece, as well as a material model for the process-induced
formation of martensite, providing equations based on empirical data. Moreover,
measurement systems providing a closed feedback loop are presented, including
a novel softsensor for in-situ measurements of the martensite content.
